Signs horseradish powder has gone bad

- Caking or damp clumps inside the jar.
- A flat, stale smell instead of sharp heat.
When in doubt, throw it out — the cost of a spoiled meal isn't worth the risk.
Best way to store horseradish powder
Horseradish powder is all about its pungency, and that sharp compound evaporates over a few months, leaving it flat. Keep it tightly sealed in a cool, dark cupboard away from heat and steam to slow the fade, and rehydrate only what you need.
